Question

What is an equation of the line star passes through the points(-8,8) and(4,-1)? Put your answer in fully reduced form

Answer 1

y2-y1/x2-x1 to find the gradient. So -1-8/4–8= -9/12. Then substitute into any of the coordinates. I chose -1=4(-9/12)+c. Rearrange to get c alone. Answer altogether is : y=-9/12x+2
